Different volume for different audio source

[firearasi]

I am working on a music app, and I will be using AVAudioPlayer and iPod library(ie MPMusicPlayerController) to play some mixed sound. Is there any api so that I can set up different volumes for these two sources of sound?

Thanks,

in my game i use 2 avaudioplayer and timer :

volumeTimer = [NSTimer scheduledTimerWithTimeInterval:0.05 target:self selector:@selector(updateVolume) userInfo:nil repeats:YES];

-(void)updateVolume {

if (volumeSlider.enabled == YES) {


[audioPlayer setVolume:volumeSlider.value];
volumeSlider.value = [[NSUserDefaults standardUserDefaults] floatForKey:@"slider"];
}

else [audioPlayer setVolume0.0)];
}
